FEED-REGULATOR FOR ROLLER-MILLS.

SFBCIFICATION forming part of Letters Patent No. 340,898, dated April 27, 1886.

Serial No. 171,551. (No model.)

To aZZ whom, it may concern: a

Be it known that I, WLADIsLAUs ST. M [EL- CAREK, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Feed-Regulators for RollerMills; andI do declare the following to be a full, clear, and exact de scription of the invention, such'as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let ters and figures of reference marked thereon, which form a part of this specification.

Figure 1 is a view in perspective of the arm J upon the shaft (1 showing the end of slotted portion R of said arm in the crank box K, of the lever 0. Fig. 2 is a plan view of Fig. 1, some of the parts being removed to show the crank-pin T. Fig. 3 is a side view of part of the roller-mill, showing the mechanism employed in the application of power to the shaker device. Fig. at is a vertical sectional view showing the rear portion of shoe DI and shaker mechanism. Fig. 5 is a detail view, and Fig. 6 is a sectional view, on the line 2 2 of Fig. 4.

My invention relates to feed-regulators for roller-mills; and it consists in the improved constructions and combination of parts hereinafter fully described, and pointed out in the claims.

Referring to the drawings, I is the shell or case of a mill, having the rollers 1 2 3 4, the shaft of the roller 3 being extended to sustain the pulley 13,which is connected with its companion pulley 12 by the belt 14. Said pulley 12 is carried upon the shaft U, the latter revolvingin the journal-box L, which is integral with, and an extension at right angles of, the lever O. Said lever is supported by its fulcrum M, and its power is regulated by the sliding weight N, having a suitable set-screw. The inner end of the shaft U has the pin T at one side of its center, fitting and revolving within the hole S in the block Q. Said block Q slides in grooves PPin the sides of the slot 1 in the enlarged portion R of the lever .I.

The lever O is provided with a crank-box, K, adapted to be filled with oil, and to receive the end It of the lever J, said crank-box being sufficiently large to permit the free oscillation of saidend R therein when the crank-pin T revolves. The upper end of said leverJ is fastened by a set-screw, 15, or otherwise, upon the shaft C, said shaft being extended through to the other side of the case I, and suitably journaled therein. Upon said shaft 0, firmly fastened by set-screws 5, are the yokes or spring-supports A A, each member of which has a triple spring composed of the blades a a and the central bladr, 7, secured together by the rivet 6. The blades 7 pass through slots in the plates B B, said plates being fastened to the feedshoes D .D. (See Fig. 6.) The feed-shoes are supported at their heels by means of the hangers E, the latter being suspended from the inner ends of the levers 9 9, which pass to the outer side of the case I, through the slots ll, and, turning at right angles, hinge upon suitable .l'ulcrums, and are adjusted by the thumbscrews 10, as shown in Fig. 3. The toes of said shoes are each provided with two supports, F F, arranged upon the inner sides of the shoes, at the corners thereof, and hinged upon the levers G G, having suitable fulcrums, which are adjusted by the thumb-screws H H. (See Fig. 6.)

It will be seen that as the pulleys 12 and 13' revolve, the eccentric motion of the pin' T upon the shaft U within the block Q produces a shaking of the lever J, which is communicated through the shaft 0 to the yokes A A and the springs terminating the same, thereby causing an oscillating or shaking motion of the plates B B and the feed-shoes connected therewith.

The weighted lever O is the device whereby the tension of the belt 14: upon the pulleys may be regulated, being tight or 1oose,according to the position of the weight N.

The manner of sustaining the feed -shoes by the supports E and F, regulated bythe levers G 9, enables the operator to control the flow of grain. Thus, by lowering the toes so that the incline of the shoes is increased, said shoes feed faster, and by lowering the heels and increasing the distance between the hoppers and the shoes the volume of feed is enlarged.

The hoppers, as shown in Fig. 6, are lettered \V.
